Possibly by trying to find a business model that can support Chrome development just like all other Chromium (and non-Chromium) based browsers?
As much as I loved Chrome when it first came out, I’ve also been well aware that Google’s backing of Chrome (and Chromium) has given it undue advantages in the browser market by effectively making everyone else compete with a loss leader. If Chrome itself cannot sustain its pace of development or even stay alive without the unlimited funding by Google, then I think that is a good thing and proof that it acting as a monopoly. Forcing Chrome to balance product velocity with revenue constraints evens the field amongst all browsers.
(edit: If Google killing competition by injecting unlimited funding into a project without needing to make a profit sounds familiar, it’s because they’ve done this for a long time. The often cited example being Google Reader.)
